esz receives accreditation certificate for calibration of exhaust emissions measuring instruments
Shortly before the end of 2018, esz AG calibration & metrology guarantees the nationwide maintenance of exhaust emission testing. With the receipt of this important DAkkS-accreditation, the company in the west of Munich is further expanding its range of services and thus ensuring compliance with the new requirements in the automotive industry. The know-how gained from over 30,000 accredited calibrations already carried out on brake test stands and test devices for headlamp settings contributed significantly to this success. When it comes to exhaust emissions measuring instruments, the market leader also relies on its proven representative concept, which was launched in 2017 and which enables technicians from manufacturers, dealers and service companies to carry out accredited calibrations on behalf of esz AG. The network, which is homogeneously distributed throughout Germany, now comprises more than 170 companies and over 650 technicians.
More room for new challenges
We have moved – from Karlsruhe to Mannheim. For the new "South West" subsidiary of esz AG calibration & metrology, this means larger premises, faster logistics and a significantly expanded service portfolio. After more than 12 years in the narrow inner city of Karlsruhe, the premises of the esz branch were closed and moved to Mannheim. The new location offers more space for new tasks and brings clear advantages: - easier and faster to reach by road and rail - sales base now with full-fledged calibration laboratory - up to ten service technicians on site - faster and more flexible order processing - closer connection to Logistik Expert Mannheim offers a perfect connection to the national and European transport network and is situated in a perfect location between Frankfurt and Stuttgart. Many large industrial companies are located in this economic area. The new premises offer additional space for a full-fledged calibration laboratory. DC/NF measurands can now be calibrated directly in Mannheim, a further expansion of the laboratory is planned in the next few months.

Munich Calibration Day 2018 - Putting an end to half-knowledge
“Half-knowledge is worse than ignorance” (Klaus Klages, German philosopher). Especially when highest precision is required. The goal of the expert seminar, which esz AG calibration & metrology organized for the fourth time, was to put an end to the half-knowledge in the calibration industry. Under the title "Mastering the basics - standard-compliant calibration", five industry specialists provided practical tips and important basic knowledge on all aspects of calibrating pressure, humidity and particle measuring devices as well as on the subject of measurement uncertainty calculation and laboratory management. On day two, the participants were given an exclusive insight into the esz laboratory in Eichenau near Munich. Munich Calibration Day 2018 took place on September 13 and 14 at the INFINITY Hotel & Conference Resort Munich. The approximately 65 participants from all over Germany – most of them responsible for test tools and quality management – assessed the event positively across the board.

esz AG participates in environmental project Ökoprofit
The subject of "environmental management" will become an integral part of the quality management system of esz AG in the future. For this purpose, an internal environmental officer has been appointed, who is the central contact person for questions, suggestions and measures within the company. First important action: esz AG participates in the state-sponsored environmental project "Ökoprofit". As part of the one-year environmental advisory program, the participating companies receive expert support in introducing an operational environmental management system. A systematic inventory is carried out and economically and ecologically sensible measures are identified. This lays the foundations for a continuous improvement process. esz AG has already implemented a number of measures. The energy supply at headquarters in Eichenau was converted to green gas, thus significantly reducing CO² emissions. Automatic paper towel dispensers in the rest rooms reduce paper waste and water savers in the faucets reduce water consumption.
